Spiral Sorrel is a easy-care plant. As an indoor plant, ensure good ventilation to aid recovery.

Unlike most plants, Spiral Sorrel has natural resistance to Curculionidae. Best treated with preventive measures rather than reactive treatment.

• ✓ Inspect and, if possible, quarantine any new plants for 2 to 3 weeks.
• ✓ Use high-quality, clean substrate and wash or disinfect pots and tools before reuse.
• ✓ Keep the environment clear by removing plant debris and stacked wood that serve as shelter.
• ✓ Adjust watering and avoid waterlogging, which exacerbates damage to weakened roots.
• ✓ Place adhesive bands in spring and summer if you had issues the previous year.
• ✓ Apply nematodes preventatively in late summer or autumn in pots and flowerbeds with a history of weevils.
• ✓ Regularly check leaf margins, as early detection of notches facilitates control.
